A Family Run Business That Values Its Customers

Novaseal has been helping customers in Fareham, Southampton, Portsmouth, New Forest, Chichester, and Hampshire and West Sussex areas with their double glazing requirements for two decades. We have the knowledge and experience to make your home improvement project a success.

We take care to ensure our stock levels are high, so we can meet the demands of our trade customers and homeowners who want to buy from us directly. Novaseal invests continually in its equipment; 70% of the machinery we use is brand new and enables us to meet customer demand.

54,000 Frames and Counting

In the last two decades, we’ve produced 54,000 frames for our homeowner and trade customers. We’ve achieved this volume without compromising on quality and by continually investing in our equipment and our people.

Although we can work to scale, we take time to build relationships with our customers. We’re never too busy to talk, and the owner of our business is always accessible, often working our trade counter during busier times.

We Invest in Our People

We’re proud of the fact that people want to work here. Novaseal trains develops and rewards the people that help make it so successful, which is probably why the average employee has been part of our team for eight years.

By retaining our staff, we’re able to help our customers. The teams that work in our manufacturing facility, behind our trade counter, and elsewhere, have the knowledge and experience needed to make our business successful.

Everything in One Place

Novaseal manufactures and supplies many double-glazing products and ancillary items for its customers. Because of this, they can access our range of doors, windows, conservatories and anything else they need.

Our expansive range – coupled together with our in-house manufacturing facility and ability to respond to scale – means that you won’t be disappointed when you choose us for your project and will only need one point of contact.

Our Products

Carefully Chosen Products

We only work with leading manufacturers. This means we can deliver products that meet the high standards our trade and homeowner customers expect and deserve. Your purchase will include a manufacturers’ guarantee for your peace of mind.

Where appropriate, our products at least meet – but often exceed – industry standards. For example, our uPVC doors and windows meet Secured by Design specification, police- backed initiative that helps our customers buy with confidence



of business from recommendations

Our commitment to manufacturing and supplying the best products, while providing the best levels of service, means that customers often seek us out based on our reputation.
